SPIGOT. l

Specification of Letters Patent.

Application led November 15, 1911. lSerial No. 860,359.

To all 'whom-it ma concern:

Be it known t at I, MATHEW ANDREW "snm, t sub'ect of Ythe Kin of Great Britain, and Vresi ent of Finch, 1n the Province of Ontario, Dominion of Canada, have invented certain newand usefulLImprovements in Spigots, of which the following is 'a specication.

My invention relates'to improvements in spigots or valves of the type adapted to be applied to any kind of liquid containing rece tacles-such as oil or solene tanks, barres, beer k or simir receptacles and the objects o my invention are to provide for the admission of air through the valve as the liquid is being withdrawn, thereby facilitating the iiow of liquid, to provide for a quick cut oli of the fluid, to provide forA the adjustment in the amount of opening of the valve and` for` locking the valve against opening; and itconsists essentially of the improved construction and arrangement of parts hereinafter descrlbed in detail in the `accompanying specification and drawings in Whichy Figure 1 is a vertical sectional view of the valve in closed position. Fig. 2 is a vertical sectional viewof the same in open position. 3 is a perspective view of the movable v ve element.

Referring now to the drawings: A represents the sleeve member of the valveadapted to be fitted to the receptacle, the outlet of which is to be controlled, and in the embodiment illustrated the sleeve member comprises a. screw threaded neck l0 and an enlarged screw threaded recess 11 in which may be located a washer or other packing element 12. The remaining portion 13 of the valve sleeve is provided with a screw threaded neck 14 which threadsinto said recess 11, and is also furnished with a delivering lport l5 and spout 16 and also an air-port 17.

According to my invention the valve stem B of the device comprises -a sliding rod 18 which reciprocates in the bore 19 of a threaded member or closure 20, said member or closure being provided with and-beingv of suitable size to-screw recess 21 into the outer portion 13 of the valve sleeve. The stem B of the valve is provided with a valve element 22 which works inthe recess' 11 and bears member 23 which reciprocates within the threaded neck landin whicharelocated the delivery port 2A and the' air port 25 adapted to register with theV rts 1`5 and 17 respectively when the valve 1s in open position, that is against the washer 12 by meansy of spiral spring 27 which abuts against the bottom of the recess-21 and bears'against the collar 28 in which is located an annular recess' 29 adapted to receive the end of said spring and in order to'limit the outward movement of the stem B a sto 30 is rovided thereon, which abuts against the lbottom of the recess 21 when the stem B is in its outermost osition. A threaded nut 31 or other manual y operated means may be employed to pull the valve stem B and valve outwardly into open position, and in the embodiment shown said nut 31 is threaded 011 the rod 18.

yThe operation is the device is as follows: In 'order to open the valve the stem B is pulled outwardly by rotating the thumb nut 31 until the delivery port 24 registers with the port 15 and the air port registers with the port 17, thus the liquid is allowed to flow from the tank under an atmos heric air pressure and from the constructlon of the device it is evident that the flow of liquid may be readily regulated by adjustment of the ports 24 and 15relative to each other and also that a continuous iow of liquid may be obtained by locking the stem B in open position by means of the thumb nut 31. The pressure of the valve element 22 on its seat and therefore the liquid tight effectiveness of the valve may be obtained by increasing the tension of the spring 27. It will also be seen that the valve may be locked against opening by merely rotating the said member or closure 2O until the stop 30 rests against the bottom of the recess 21 while if an immediate iow of liquid is desired the stem B may be merely pulled outwardly without rotating the nut 31.

As many changes could be made in the above 'construction and many apparently widely different embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is-intended that all mat Patented Feb; 25, 1913.

prising a reciprocating valve provided with a tubular member provided with a fluid delivery port and an air port, a pipe connecting said airport to the interior of the tank, a sleeve member supporting said valve, and provided with an air port and a delivery portvadapted to registerwith the" air port and delivery port respectively of the tubular member upon the reciprocation of saidtubular member.

2. In combination a receptacle, aV spigot comprising a reciprocating tubular member through which the liquidis adapted to ow, and a valve elementI on' said tubular member, a sleeve member supportingsaid tubular member and provided with a valve seat for said valvefelement, means for normally holding the 'valve element in closed position and means for Aadmitting air into the receptacle during the' tiow of the liquid.

3.' In.` combination a` receptacle, a spigot comprising a reciprocating tubular member provided with a fluid delivery port, a sleeve member supporting said tubular member and provided with a fluid delivery port adapted to register. with the port of said tubular member, a spring held valveelementon the tubular member adapted to control the passage of fluid through both delivery ports, means foi-'admitting air into the receptacle during the passage of fluid and means for controlling the movement of the valve element. -v

4. In combination a receptacle, a spigot comprising 'a reciprocatingV tubular member adapted to permit the flow, of Huid therethrough, a sleeve vmember supporting said tubularmember and provided'lwith a valve seat, packing means-located in the'valve seat,

a member or closure threadedin Said sleeve',

member,i a valve stem adapted to extend 'through said member or closure, a spring held valve element. mounted on the stem and connected to the tubular member and adapted to normally rest in the valve seat and means foradmitting air into the'receptacle during the passage of uid.

5. In combination a receptacle, a spigot I comprising a reciprocating tubular member provided with an air port and a lfiuid lde'- livery port, a 4pipe connecting the' air port i to the interior ofthe receptacle, a sleeve member supporting the tubular member inserted Ainto the receptacle, 'a body portion threaded into the sleeve member and provided withan air port and a fluid delivery port adapted to register respectively with 'i tubular member secured to the stem and a' spring seated in said recess and bearing against ,saidJ valve element to normally close the passage through the ports, means for limiting. the outward movement of the stem ,and adjustable threaded means' for operating said stem. v

' 6. In combination a receptacle, a spigot comprising a sleeve member inserted into the receptacle, and provided with an air port and a delivery port, a tubular member reciprocably mounted within said sleeve member andprovided with an air port and a de livery port, means for reciprocating said tubularmember Within said sleeve whereby the respective air ports and delivery ports of said tubular member and said sleeve member are brought into register, and means for locking said tubular member in any adjusted position.

In witness .whereof I have hereunto set my hand in the presence of two witnesses.
